A speedboat starts from rest and accelerates at 2.01 m/s2 for 6.6 s. At the end of this time, the boat continues for an additional 7.1 s with acceleration 0.44 m/s2. Following this, the boat accelerates at 1.19 m/s2 for 7.8 s. All the time the boat moved along a straight path.

(a) What is the boat's speed at the end of its path?

(b) Find the total displacement of the boat.
